ULTRASONIC BLOOD FLOW DIAGNOSING DEVICE FOR BYPASS GRAFT EVALUATION

摘要

PROBLEM TO BE SOLVED: To provide an ultrasonic blood flow diagnosing device, accurately, quantitatively and simply diagnosing anatomical and hydrodynamic disease condition of an anastomotic region during blood vessel bypass operation.;SOLUTION: In the bypass operation performed for a blood vessel where constriction or obturation is caused due to arterial sclerosis, an ultrasonic probe is brought into contact with the bypass blood vessel (graft) and the hydrodynamic constriction degree of the anastomotic region is calculated by a multipoint doppler method, and further constriction caused in the anastomotic region is anatomically and quantitatively evaluated by an ultrasonic tomographic method, whereby accuracy of anastomosis is quantitatively diagnosed during the operation to improve the operational result.;COPYRIGHT: (C)2008,JPO&INPIT
